Description

Automobile flywheel

Technical Field

The application relates to the technical field of automobile parts, in particular to an automobile flywheel.

Background

The flywheel of automobile is a cast iron inertia disc with large mass, which stores energy and supplies the requirement of non-working stroke to drive the whole crank rod structure to cross the upper and lower dead points, thus ensuring the uniformity of inertia rotation and output torque of the crankshaft of the engine, and helping to overcome the compression resistance in the cylinder during starting and maintain the continuous running of the engine during short-term overload by means of the self-rotating inertia force. The flywheel has two main functions: firstly, energy is stored for the engine, and the stored energy is used for enabling the engine to complete a non-working stroke; secondly, the torque and the rotating speed output to the outside by the engine are as uniform as possible.

Flywheel assemblies are important engine components that operate at up to hundreds of revolutions per minute, and as a result, the flywheel often suffers from fretting damage, flexing, and loosening of the ring gear after prolonged use. The existing flywheel is single in structure, when the flywheel part is damaged, the whole flywheel main body needs to be replaced, and the production, use and maintenance costs of the flywheel are greatly improved.
